The preservative assembly is adapted to automatically transfer at least a portion of, respectively, the preservative solution, if present, and the gas to the collection assembly under a force of gravity once fluid flow communication is commenced between the preservative container and the collection assembly. Further, when the collection container contains at least a portion of the biological liquid and a transferred portion of the preservative solution, if present, and the gas, the collection container is adapted to automatically transfer at least a portion of, respectively, the biological liquid, the preservative solution, if present, and the gas to the filtration assembly under the force of gravity once fluid flow communication is commenced between the collection container and the filtration assembly.
